List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1 Read and interpret job requirements and locate materials | 1.1 Appropriate processes are identified and confirmed, and original is assessed to determine scanner settings 1.2 Appropriate chemicals, inks, materials and/or equipment are selected according to job specifications |
2 Set up machines/equipment | 2.1 Pre-startup checks are completed and documented according to enterprise procedures 2.2 Raw materials or feed lines are checked to ensure availability 2.3 Machine and equipment operation is verified according to enterprise procedures |
3 Maintain blending or homogenising process | 3.1 Mix is completed according to enterprise procedures and work health and safety (WHS) requirements 3.2 Materials are added to process according to job specifications 3.3 Quality inspection and sampling is carried out according to enterprise procedures 3.4 Adjustments to mix or equipment are made to correct identified quality problems 3.5 Records, log or checklists are completed according to enterprise procedures |
4 Shut down | 4.1 Correct shutdown sequence is followed according to manufacturer’s specifications and enterprise procedures 4.2 Product or materials used in manufacture are removed from operating area where appropriate 4.3 Solid and liquid waste is removed from operating area and recycled or disposed of, where required, according to regulatory requirements and enterprise procedures |
5 Clean up | 5.1 Equipment cleaning requirements are identified 5.2 Correct equipment or materials for manual or mechanical cleaning are selected 5.3 Cleaning is undertaken according to enterprise procedures and WHS requirements |
Evidence of the ability to:
locate, interpret and use information from various sources to carry out tasks
use a mixer disperser OR a bead mill OR an automatic ink dispensing system to blend TWO batches of chemicals OR tint TWO batches of ink intermediates or concentrates according to manufacturer’s and job specifications, health and safety requirements and enterprise procedures including:
selecting, checking and setting up chemicals, ink, materials and equipment
carrying out quality checks during blending and making required adjustments
completing required records
cleaning and removal of waste.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
list and briefly describe the purpose of each of the listed items used in the blending of chemicals for ink or varnish manufacture:
high and low speed dispersers
pan washer or scrubbers
pumps
valves
automatic ink dispensing system
homogeniser
de-ioniser
identify potential hazards in the selection, preparation and clean up of materials and equipment for blending chemicals, including the correct use of safety equipment
identify environmental issues that need to be considered when working with the range of materials used in chemical blending and tinting
describe the enterprise procedures for:
preparing containers and equipment for blending and tinting
adding chemicals and constructing correct colours according to formulae
testing conductivity, viscosity and pH, where in-process testing is conducted
sampling and testing
a planned shutdown
explain the purpose and process of:
homogenisation
de-ionising water when it is to be used in the blending process
batch coding systems
outline the checks to be made when measuring chemicals for blending
explain the factors that determine the position of the mixing head when blending
list and describe problems that may occur in the tinting process and how these may be overcome.
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the ink manufacture field of work and include access to:
enterprise documents and policies and procedures
materials and equipment used in the blending process
cleaning chemicals, materials and equipment.
Assessors must satisfy NVR/AQTF assessor requirements.
